All procedures were performed by 1 surgeon and assessments done by masked examiners. ARP was performed with an allograft and a resorbable collagen membrane. The presence of granulomatous tissue remnants after debridement was recorded. Cone\u2010beam computed tomography (CBCT) and ultrasound (US) scans were taken during the healing phase up to 16\u2010week visits. Bone cores were retrieved from implant osteotomies for histologic analysis.

The jawbone healing varies, depending largely on the ability to remove the etiology, socket features, extent of surgical trauma, and wound stability. Healed jawbone with good quality is favorable for easiness of implant placement and could be related to maintenance of long\u2010term implant health. The surgical microscope with high magnification (up to \u223c25\u00d7) and co\u2010axial illumination is ideal for assistance in the removal of granulomatous tissue that is believed to interfere with healing, performance of minimally invasive extraction, and stabilization of the wound with meticulous tissue management and fine sutures. This study compared the use of the surgical microscope to dental loupes for ARP in a randomized controlled design. The microscope\u2010assisted ARP is associated with a significantly higher chance of removing granulomatous tissue, favorable early healing, and similar crestal bone quality. Removal of granulomatous tissue is significant for immediate implant placement. This study serves as a model for testing the benefits of the surgical microscope for encouraging early healing in more challenging intraoral surgical procedures.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jper.24-0081","type":"journal-article","created":{"date-parts":[[2024,10,15]],"date-time":"2024-10-15T04:44:22Z","timestamp":1728967462000},"page":"230-240","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Clinical
